- So I'm going to start out by exploring the physicalcomponents of the 1841 router.We're going to start by first looking at thephysical components on the front of the router.So the front of the router includes the Cisco brand logo,it will be located on the top left,and the type of router would be indicated on the top right.There are two system LEDs,the system power LED, which is either off,which means there's no power,or it's blinking green,which indicates that the router is booting.

There's also a system LED, and that will either be off,which means no traffic is passing through the router,or it would be on, which means that the router'scurrently moving traffic through and out one of the ports.On the back plane of the Cisco routeryou're going to find a power input,it's on the right-hand side,and that's where you actually plug in the AC powerfrom the wall.There's an on and off switch,and currently the on and off switch is greenwhich means that this router is powered on.

There are two management ports,to the left, one is a console portand one is an AUX port.There are two FastEthernet ports to the left of that,as well as the LED lights that showwhether or not those ports are in use.To the left of that is a USB port,for plugging in a USB drive.And then there are two network card expansion slots.

There's a slot called zero in the top right,and there's a slot, slot one, which is in the top left.The one on the right has a (mumbling) installed in itAnd that is for use to connect upto your wide area network with a serial cable.And the other one has a cover on it,and that's best practice is to keep a coveron any of the open slots,but if you have such a need you can put ina different card to expand the capability of the router.Below slot one, there's also a compact flash slotand directly to the right of that is a little LEDthat would light up if that compact slot has a card in itand it is being used.

To the right of that is an advanced integration module lightand that would be on if an advanced integration moduleis actually installed in the router.Above that is a little Kinsington security slotand it's used to attach a security cableso that you can physically secure the routerif it's in a location where it could be mocked off with.And then finally, on the very right-hand sideover by the power cable,is a chassis ground connectionso that you can attach a ground cablefor the router if it's installed in a rack.

Learn how to configure a Cisco router to transmit data between local area networks and connect to the Internet. In this course with Denise Allen-Hoyt you'll find out how to configure a Cisco router via the command-line interface using an out-of-band connection. She'll explain how to access the router's three modes—user EXEC, privileged EXEC, and global configuration—and use commands to configure essential settings. In the final chapter, she'll demonstrate how to verify and save your configuration so when the router is shut down or reloaded the settings are maintained.
